Nerlens Noel, Kentucky center: He has the most defined NBA skill in this draft – a gift for blocking shots that averaged over four per game before he suffered that knee injury last winter. Noel likely wouldn’t be available before the middle of next season, but teams will still give him strong consideration in the top three. He’s not particularly skilled at the offensive end, and he needs more lower-body strength to hold up in the scrums under the basket at the NBA level. But as a rim-protector, he’s quite impressive.
